Title: Antenna
Inventor: HIBINO KUNIO
IPC: H04B17/00
Filed: 1982-03-15
Abstract: PURPOSE:To detect high-frequency power injecting to an antenna element accurately, by incorporating a high-frequency power detection circuit in the inside of an antenna base. CONSTITUTION:A telescopic antenna 1 is fixed at a cylindrical upper part 23 of  an inverted funnel-shaped hollow antenna base 2, and a high-frequency connector C and a high-frequency power detector 3 are incorporated at the bottom of a lower part 21 of the base 2. The detector 3 comprises conductors 311, 312 forming a directional coupler 31, both conductors are electromagnetically coupled, a travelling wave is taken out from a termination resistor P1 and a reflected wave is taken out from a termination resistor R1, respectively and high-frequency components are eliminated at by-pass capacitors P4, R4 through diodes P2, R2, and a DC component only is transmitted to a radio device main body from DC component output terminals P, R through DC component cables OUTP and OUTR. Thus, the loss due to coaxial cables is not required to take into consideration and the power given to the antenna 1 is detected accurately.

Title: Communication of vbi data in digital television data stream
Inventor: NUBER RAY
IPC: H04N19/89
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To obtain a digital television(TV) data transporting syntax for storing user information at a vertical blanking interval(VBI) by preparing a process or the like for adding a count value indicating the quantity of user information to a user data syntax. SOLUTION: Ray digital video data inputted from a terminal 10 to a serial receiver 12 are converted into continued data by a parallel format. These data are buffered in a butter 14. A video passer 16 judges the syntax of continuous data and removes information for identifying raw luminance and color luminance instensity data. The luminance and color luminance intensity data are inputted to a demultiplexer 18 and divided into a data part corresponding to the VBI of continuous video frames and the active video part of these frames. The demultiplexer 18 determines also whether entered data stream synchronization is lost or not, and when it is lost, outputs a synchronization loss signal to a video compressing processor 22 for receiving also active video data to be compressed.

Title: Method of correcting clearance between rotors for root's blower or pump
Inventor: IWASE TAKAHIRO
IPC: B24B31/00
Filed: 1984-02-29
Abstract: PURPOSE:To make it possible to correct the clearance between rotors in pair to make the clearance uniform allower the angular phase of the rotors, by feeding a suspension liquid prepared by mixing grinding particles in a liquid into the inlet port of a casing jig to which the pair of rotors are attached, and as well by rotating the rotors at a uniform speed in the reverse directions with respect to each other to discharge the suspension liquid therefrom. CONSTITUTION:Rotors 36, 38 are rotated at the same speed with respect to each other while maintaining 90 deg. phase angle difference therebetween in the directions with respect to each other, by meshing a gear 34 with a gear 76 after a rotor assembly 50 is attached to a casing jig 52, and therefore a suspension liquid 72 is sucked and is discharged into a discharge pipe 68. Since these rotors 36, 38 are manufactured in sizes which are slightly larger than their normal sizes, there are parts where the rotor are made in direct contact with each other and where particles in the suspension liquid 72 are made compact so that the assembly 50 rotates together with elastic deformations in both rotors 36, 38, a seal member 60, a bearing 22, etc. Accordingly, upon initiation of rotation the contact area between the rotors 36, 38 is large so that a slip occurs due to a certain difference between the pheripheral speeds of both rotors. However, since the suspension liquid exists between the rotors and the rotational speeds thereof is low, no seizing occures and as well the rotors are ground by the particle therebetween.

Title: Method and device for pattern recognition
Inventor: YAGI HIROYUKI
IPC: G06F15/18
Filed: 1995-02-28
Abstract: PURPOSE: To classify classes with high precision through a relatively small number of learning operations by reducing an area which is already set in a multidimensional space independently about respective feature axes and, preferably, independently about the plus and minus directions of the respective feature axes when the area is reduced. CONSTITUTION: A point P1 which belongs to a class 1 and a point P2 which belongs to a class 2 are different in radius value from each other about a feature axis X, but their radius values overlap with each other about a feature axis Y. In an RCE network, the points have the same radius value about all feature axial directions and the radii are so reduced that the radius values in areas belonging to different classes do not overlap with one another, but different radius values are allowed by the feature axes in this case and when the classes are classified by the features in one feature axial direction, the radii are allowed to overlap with one another as to other feature axial directions. Consequently, high-precision class classification is enabled by a relatively small number of learning operations.

Title: Exchange system
Inventor: NAKANO MOTOHIRO
IPC: H04M3/42
Filed: 1990-02-21
Abstract: PURPOSE:To reduce the load of a high-order terminal by tentatively releasing connection restriction from the high-order terminal to a low-order terminal and allowing the low-order terminal to directly originate. CONSTITUTION:When an extension A set up as a specific class is to execute international communication with an international origination source, the extension A internally calls an extension B set up to a superspecific class to transmit information indicating the requirement of international origination. Then the extension B imparts an origination class equivalent to that of itself to the extension A. At the time of starting talking with the international origination source, the origination class of the extension A is returned to the specific class again. Thereby, reorigination can be attained even when talking with the international origination source is not formed.

Filed: 1982-03-17
Abstract: PURPOSE:To quantitatively obtain alumina having a desired alpha-BET value with high thermal efficiency by charging part of powdered alumina hydrate into the higher temp. section of an airborne calcining furnace to form crystalline alumina and by charging the remainder into the lower temp. section to form gamma- alumina. CONSTITUTION:A bypass is attached to a shoot 11 for charging preheated alumina hydrate as a powdered starting material, and a distributing conveyor 14 is attached to the bypass. The preheated starting material distributed by the conveyor 14 is charged into the lower temp. section of an airborne furnace 4 through a shoot 11a optionally after distribution to the upper and down stream sides of a duct 5 through shoots 11b, 11c in accordance with a desired temp. of a gas flow. The dividing ratio between the higher temp. section of the airborne furnace 4 and the conveyor 14 is regulated by placing a damper or the like. Alumina having a desired alpha-BET value in a wide range and consisting of crystalline alumina and gamma-alumina can be obtd. The crystalline alumina consists of theta-alumina and alpha-alumina. Since uniform mixing is carried out in the gas flow, the formation of fine powder and ununiform mixing are not caused in the mixing stage unlike a conventional method.
